Character Copy Kata

Introduction

This is a legacy code kata, to practice breaking the dependencies (i.e., dependency-breaking techniques)

Description

This is an REPL program:

Read from the console
Evalutate the line (Identity function)
Print the evaluation
Loop (again)

Tasks

Adding tests

Add tests for the functionality

Evaluation improvement

Detect bad words (read them from a CSV file, one word per line). Do not alter the printing yet.

Printing improvement

When detecting bad words, print "****" (one star for each character). The detection invalidates the whole line, not only the bad word itself
